“We continue to gain share, installing a record amount of solar energy and home batteries this quarter, driven by over 40% growth in our direct business,” said Lynn Jurich, Sunrun’s chief executive officer. “We have now delivered clean, resilient and affordable energy to more than 202,000 customers. Given our market leadership position and enormous opportunity for growth, we are investing heavily to strengthen our competitive advantages in customer acquisition and experience.”

Adoption of New Accounting Standards

On January 1, 2018, Sunrun adopted FASB’s new accounting standards for contracts with customers (“Topic 606”) and lease accounting rules (“ASC 842”), using retrospective methods. Adoption requires that prior financial results are recast to reflect the new standards. Unless otherwise specified, financial results for both the second quarter of 2018 and the second quarter of 2017 are presented in this release under Topic 606 and ASC 842. The financial results for the second quarter of 2017 may differ from those previously reported.

Key Operating Metrics

In the second quarter of 2018, MW deployed increased to 91 MW from 76 MW in the second quarter of 2017, a 20% year-over-year increase.

Creation Cost per watt was $3.12 in the second quarter of 2018 compared to $3.37 in the second quarter of 2017, an improvement of 7% year-over-year. The presentation of Creation Cost for the second quarter of 2017 remains as previously reported, as the calculation due to the adoption of the new accounting standards and the resulting recast financials would have resulted in immaterial changes in the Creation Cost for that period.

NPV per watt in the second quarter of 2018 was $0.98 compared to $1.10 in the second quarter of 2017.

NPV created in the second quarter of 2018 was $77 million, a 4% increase from $74 million in the second quarter of 2017. Project Value per watt was $4.10, compared to $4.47 in the second quarter of 2017.

Gross Earning Assets as of June 30, 2018 were $2.6 billion, up $684 million, or 36% since June 30, 2017. Net Earning Assets as of June 30, 2018 were $1.3 billion, up $195 million, or 18% from the prior year.

Financing Activities

As of August 9, 2018, closed transactions and executed term sheets provide us expected project debt capacity into the first quarter of 2019 and tax equity capacity into the second quarter of 2019.

Second Quarter 2018 GAAP Results

Customer agreements and incentives revenue grew 58% year-over-year to $91.6 million. Solar energy systems and product sales increased 9% year-over-year to $78.9 million. Total revenue grew to $170.5 million in the second quarter of 2018, up $39.9 million, or 31% from the second quarter of 2017.

Total cost of revenue was $122.0 million, an increase of 15% year-over-year. Total operating expenses were $205.5 million, an increase of 20% year-over-year.

Net income available to common stockholders was $7.4 million in the second quarter of 2018, compared to $18.3 million in the second quarter of 2017.

Diluted net earnings per share available to common stockholders was $0.06 per share.

Forward Looking Statements

This press release contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995, including statements regarding our market leadership, competitive advantages, investments, market adoption rates, our future financial and operating guidance, operational and financial results such as growth, value creation, MW deployments, gross and net earning assets, project value, estimated creation costs and NPV, and the assumptions related to the calculation of the foregoing metrics, as well as our expectations regarding our growth and financing capacity. The risks and uncertainties that could cause our results to differ materially from those expressed or implied by such forward-looking statements include, but are not limited to: the availability of additional financing on acceptable terms; changes in the retail prices of traditional utility generated electricity; changes in policies and regulations including net metering and interconnection limits or caps; the availability of rebates, tax credits and other incentives; the availability of solar panels and other raw materials; our limited operating history, particularly as a new public company; our ability to attract and retain our relationships with third parties, including our solar partners; our ability to meet the covenants in our investment funds and debt facilities; and such other risks identified in the reports that we file with the U.S. Securities and Exchange Commission, or SEC, from time to time. All forward-looking statements in this press release are based on information available to us as of the date hereof, and we assume no obligation to update these forward-looking statements.

(2) Net Earning Assets for the period ending June 30, 2017 reflects changes owing to the adoption of new accounting standards.

(3) The pass-through financing obligation used to calculate Net Earning Assets is reduced to the extent we expect the liability to be eliminated when the pass-through financing provider receives investment tax credits on assets it has funded, at which time the value of the credits is recognized as revenue. This amount is reflected in the current portion of the pass-through financing obligation. In the second quarter of 2018 the adjustment was $36.2 million.

(4) Creation Cost for the period ending June 30, 2018 excludes a non-recurring item of $1.9 million for settlement of the consolidated state court class action lawsuit related to the IPO.

(5) The presentation of Creation Cost for periods commencing with March 31, 2018 reflects changes made to the calculation owing to the adoption of new accounting standards. The presentation of Creation Cost for periods prior to March 31, 2018 remain as previously reported, as the new calculation and resulting recast financials would have resulted in immaterial changes in the Creation Cost for such prior periods.

Definitions

Creation Cost includes (i) certain installation and general and administrative costs after subtracting the gross margin on solar energy systems and product sales divided by watts deployed during the measurement period and (ii) certain sales and marketing expenses under new Customer Agreements, net of cancellations during the period divided by the related watts deployed.

Customers refers to all residential homeowners (i) who have executed a Customer Agreement or cash sales agreement with us and (ii) for whom we have internal confirmation that the applicable solar energy system has reached notice to proceed or “NTP”, net of cancellations.

Gross Earning Assets represent the remaining net cash flows (discounted at 6%) we expect to receive during the initial term of our Customer Agreements (typically 20 or 25 years) for systems that have been deployed as of the measurement date, plus a discounted estimate of the value of the Customer Agreement renewal term or solar energy system purchase at the end of the initial term. Gross Earning Assets deducts estimated cash distributions to investors in consolidated joint ventures and estimated operating, maintenance and administrative expenses for systems deployed as of the measurement date. In calculating Gross Earning Assets, we deduct estimated cash distributions to our project equity financing providers. In calculating Gross Earning Assets, we do not deduct customer payments we are obligated to pass through to investors in pass-through financing obligations as these amounts are reflected on our balance sheet as long-term and short-term pass-through financing obligations, similar to the way that debt obligations are presented. In determining our finance strategy, we use pass-through financing obligations and long-term debt in an equivalent fashion as the schedule of payments of distributions to pass-through financing investors is more similar to the payment of interest to lenders than the internal rates of return (IRRs) paid to investors in other tax equity structures. We calculate the Gross Earning Assets value of the purchase or renewal amount at the expiration of the initial contract term assuming either a system purchase or a five year renewal (for our 25-year Customer Agreements) or a 10-year renewal (for our 20-year Customer Agreements), in each case forecasting only a 30-year customer relationship (although the customer may renew for additional years, or purchase the system), at a contract rate equal to 90% of the customer’s contractual rate in effect at the end of the initial contract term. After the initial contract term, our Customer Agreements typically automatically renew on an annual basis and the rate is initially set at up to a 10% discount to then-prevailing power prices. Gross Earning Assets Under Energy Contract represents the remaining net cash flows during the initial term of our Customer Agreements (less substantially all value from SRECs prior to July 1, 2015), for systems deployed as of the measurement date.

Gross Earning Assets Under Energy Contract represents the remaining net cash flows during the initial term of our Customer Agreements (less substantially all value from SRECs prior to July 1, 2015), for systems deployed as of the measurement date.

Gross Earning Assets Value of Purchase or Renewal is the forecasted net present value we would receive upon or following the expiration of the initial Customer Agreement term (either in the form of cash payments during any applicable renewal period or a system purchase at the end of the initial term), for systems deployed as of the measurement date.

MW Deployed represents the aggregate megawatt production capacity of our solar energy systems, whether sold directly to customers or subject to executed Customer Agreements, for which we have (i) confirmation that the systems are installed on the roof, subject to final inspection or (ii) in the case of certain system installations by our partners, accrued at least 80% of the expected project cost.

Net Earning Assets represents Gross Earning Assets less both project level debt and pass-through financing obligations, as of the same measurement date. Because estimated cash distributions to our project equity financing partners are deducted from Gross Earning Assets, a proportional share of the corresponding project level debt is deducted from Net Earning Assets.

NTP or Notice to Proceed refers to our internal confirmation that a solar energy system has met our installation requirements for size, equipment and design.

Project Value represents the value of upfront and future payments by customers, the benefits received from utility and state incentives, as well as the present value of net proceeds derived through investment funds. Specifically, Project Value is calculated as the sum of the following items (all measured on a per-watt basis with respect to megawatts deployed under Customer Agreements during the period): (i) estimated Gross Earning Assets, (ii) utility or upfront state incentives, (iii) upfront payments from customers for deposits and partial or full prepayments of amounts otherwise due under Customer Agreements and which are not already included in Gross Earning Assets and (iv) finance proceeds from tax equity investors, excluding cash true-up payments or the value of asset contributions in lieu of cash true-up payments made to investors. Project Value includes contracted SRECs for all periods after July 1, 2015.

Unlevered NPV equals the difference between Project Value and estimated Creation Cost on a per watt basis.

*Estimated savings based on a projected annual utility rate increase of 3.16% over the life of the system. Actual savings will vary. Savings depends on several factors, including product type, system production, geography, weather, shade, electricity usage, full utilization of the 30% solar Investment Tax Credit by the system owner, and utility rate structures and rate increases. Analysis based on customers who enrolled with Sunrun between October 15, 2014 and October 15, 2015.
